Yuck, we're clearly filtering too much. :)

So let's rename that amd_filter_mce() to something else since it is
static and only used in that file. Maybe something like

        if (ignore_mce(m))
                return NOTIFY_STOP;

so that we can keep the "filter" notion all reserved to the core MCA
code and there's no confusion.

And then amd_filter_mce() is free to be used in the core code.

Thx.
